9 Claims.

My. invention relatesy to new and useful improvements in automatic speedcontrol meansI for automotive vehicles.

An important object of my invention is to provide a device forcontrolling and regulating the maximum speed of an automotive vehicle.

Another object of my invention is the provision oi a device of theabove-mentioned character that is automatic in its action to permit agreater quantity of fuel to be injected into the carburetor when thevehicle is rapidly accelerating below the maximum speed for which thedevice is set.

Still another object of my invention is the provision of a device of theabove-mentioned character that will automatically permit a greaterquantity of fuel to be injected into the carburetor when the vehicle isascending an incline.

Yet another object of my invention is the provision of a device forcontrolling and regulating the speed of an automotive vehicle that maybe effectively operated independently of the conventional throttle valveof the vehicle and that will in no Way interfere with the actuationoroperation of the same.

A further object of my invention is the provision of a device of theabove-mentioned character that may be readily and expeditiously appliedto vehicles already manufactured and in use.

A yet further object of my invention is the provision of a device of theabove-mentioned character that is simple in construction and that iseicient and efficacious in the performance of its duties.

Other objects and advantages of my invention will be apparent during thecourse of the following description.

In the accompanying drawings, wherein for the purpose of illustration,is shown a preferred embodiment of my invention, the numeral Idesignates the carburetor of an automotivey vehicle having theconventional gas feed line II, throttle actuating lever I2 and lthrottlerod I3. The carburetor is formed With a lower flange I4 normallyregisterable with the flange I of the intake manifold I6 and which isadapted tobe connected thereto by means of threaded bolts 23, or thelike.

The numeral I'I designates a casing adapted to house the working partsembodying my invention. The casing includes a substantially cylindricalvertically disposed sleeve portion I8 havingl upper and lower peripheralflanges I9 kand 2U adapted to register with the flanges I4 and I5 of thecarburetor and intake manifold respectively. The flanges I9 and 20 aresubstantially diamond-shaped in plan and are provided adjacent the endsthereof with openings 2l and 22 ladapted to align with openings in theflanges which integrally connects the same with `the sleeve. The Wall 24includes aV peripheral flange 21 which defines a central horizontallydisposed chamber 2K8 which is enlarged at the end 29 thereof to form achamber 38 laterally of the sleeve I8.

The forwardly extending portion 25 of the wall is substantially circularin planand the flange 21 defines an enlarged cupular chamber 3| thelower portion of which communicates directly with the central passage28. The flange 21 is provided at spaced intervals therearound with lugs32 having threaded recesses 33 therein adapted 'to register with theopenings 34 in the front cover 35 and to receive the threaded bolts 36which hold the cover securely in place.

` The pintle 43 is positioned transversely of the vertical passage 31 ofthe sleeve I8 with ythe end 38 thereof journaled in the recess`39`forrned in the inner wall of the passage and with the end 40 thereofextending through the sleeve I8 and into the chamber 30 to receive thelever arm 4I.

A throttle valve 42 is positioned within. the passage `3l and issuitablyfastened to the pintle 43.

Thesubstantially disk-shaped pendulum o-r weight 44 is positioned in thechamber 3| and pendulously mounted on the boss 45 integrally formed onthe wall 24. The lower portion of the disk is stepped outwardly as at 4Sto greatly increase the weight of the lower portion of the pendulum,land an abutment 41 is formed on its lower periphery to engage the stopmember 48 preferably integrally formed on the inner periphry of theflange 21, as illustrated in Figure 2. The stop member 48 engages theabutment 41 to hold the weight slightly olf center in the direction ofthe throttle valve 42 in order to normally assure the engagement of theabutment therewith, and the upper portion of the pendulum is providedwith a plurality of arcuately spaced openings 49 to permit adjustment ofthe saidV i pendulum relative to the stop 48.

The companion link members 5|! and 5| are joined for longitudinaladjustment Vrelative to each other, and the end 52 of the link4 5|)` ispivotally connected to the pendulum adjacent the lower periphery thereofand at a point diametrically opposed to the middle opening 49. The end53 of the link 5| is provided with spaced extensions 54 and 55 whichslidably receive the pin 56 extending outwardly from the free end of thelever arm 4|. The end 51 of the link member 5|] is provided with anelongated slot 58 which slidably receives the pin 59 carried by the link5| and the end E0 thereof is provided with a vertical slot 6| whichreceives the pin 56 of the lever arm 4| to securely hold the samebetween the extensions 54 and 55 of the link member 5|.

When the device is interposed between the carburetor |0 and intakemanifold IB, as illustrated in Figure l, the throttle valve 42 may bepositioned within the passage 31 to control the flow of fuel from thecarburetor to the intake manifold; the throttle of the carburetor may beactuated in the conventional manner to control the flow of fueltherethrough. By adjusting the link members 50 and 5| relative to eachother, the lever arm 4| may be acted upon to selectively position thethrottle valve 42 for control o-f the vehicle at different predeterminedspeed limits. The heavy lower end of the pendulum 44 will assure theengagement of the abutment 41 with the stop 48 tol normally hold thevalve 42 in the selected position and to prevent an excess of gas fromflowing through the passage 31 and into the intake manifold, thuseffectively and efficaciously controlling and regulating the maximumspeed of the vehicle.

When the vehicle is being rapidly accelerated, the inertia of theweighted pendulum 44 will cause the same to swing toward the throttlevalve 42 and to move the same to a relatively open position, thuspermitting a greater quantity of fuel to be injected by the carburetorinto the intake manifold. When the forward impetus of the vehicle hasbeen checked and the vehicle is traveling at an even rate of speed, theheavy lower portion of the pendulum will cause the abutment 41 to oncemore engage the stop member 48 for control of the vehicle. 'I'hependulum will be similarly actuated when the vehicle is ascending anincline. The engine will require a greater quantity of gas and thependulum will swing in the direction of the valve to open the same andto permit the carburetor to discharge a ciously control and regulate themaximum forward speed of the vehicle.

It is to be understood that the form of my invention herewith shown anddescribed, is to be taken as a preferred example of the same, and thatvarious changes in the size, shape and arrangement of parts may beresorted to without departing from the spirit of my invention, or thescope of the appended claims.
